abstract:
In this paper, we prove an averaged version of an algebraicity conjecture of Gross and Zagier concerning the values of higher Green's function at CM points. Furthermore, we give the factorization of the ideal generated by such algebraic value in the spirit of the famous work of Gross and Zagier on singular moduli.
